Unify the scripts for wiping and initializing the database

[sjoqvist]

There are multiple scripts for wiping and initializing the database, which might be confusing unless you already know how everything should be set up. One problem to solve if the scripts are to be merged, is how the new script should be maintained when there are different services that all have an interest in it.

Here are examples of scripts touching the database.

• create_icat_instance.sql
• code_analyzer/importConfig.py
• code_analyzer/populate.sql
• code_analyzer/wipe_tables.sql
• misc_scripts/initialize_db_start_katalyze.php
